How come steel is more elastic than rubber ?
A steel ball does not bounce as much as a rubber or tennis ball. How do you define elasticity? One fiber of a spider web is stronger than a steel wire of the same dia. - is this true ?
Please explain in some detail.
Elasticity is the capability of an object to return to its former shape once a load inducing strain is removed.
If you were to drop a steel ball on a very hard surface, it would probably bounce higher than than rubber. If you drop it on a softer surface, because it would deform less, then the surface it is to bounce off will be the one deforming, so the bounce would be a function of the elasticity of the floor, not of the ball.
A strand of silk is indeed stronger than a steel wire of the same diameter. The reason is that metal uses metallic bounds which is not as strong as the covalent bounds in a macro-molecule like the ones in silk. This also explains why Kevlar, carbon fiber, and carbon nanotubes are also stronger than steel.
